What Causes the Squeaking Noise from the Right Rear Wheel of the Car?
2 Answers
If the right rear wheel of the car makes a squeaking noise, especially when driving over bumpy roads, it is likely an issue with the suspension system. The owner can check whether the upper and lower pads of the spring have aged, causing the spring to collide with the metal support and produce noise. Additionally, inspect the aging condition of the rubber components at the connections of various suspension links. It is also necessary to check if there is any oil leakage from the rear shock absorber. If oil leakage is present, the shock absorber can no longer function effectively. Examine whether the rubber bushings of the shock absorber's upper and lower mounting bolts are loose. If they are, they need to be replaced or securely fastened. Check all the bolts on the chassis, rear axle, and tires for looseness, and tighten any that might be causing the noise. If the dust cover has hardened or elongated, causing friction noise, the excess part of the dust cover should be trimmed off. Below are the common causes of noise from shock absorbers in practical use: 1. Shock absorber and leaf springs: Noise may result from collisions between the shock absorber and leaf springs, frame, or axle, damaged or missing rubber bushings, deformation of the shock absorber dust cover, or insufficient oil. Identify the cause and repair accordingly. 2. Shock absorber: The owner can drive the car on rough roads for about 10km and then stop to touch the shock absorber housing. If it is not warm enough, it indicates there is no internal resistance, and the shock absorber is not working. Add an appropriate amount of lubricating oil and test again. If the housing becomes warm, it means the shock absorber lacks oil internally and should be refilled. Otherwise, the shock absorber may be faulty.
Having driven for decades, a squeaking noise from the right rear wheel is most commonly caused by issues with the braking system or suspension. If the brake pads are worn out or there's sand trapped, you'll hear a squealing sound when braking—it's essential to inspect the rear wheel's brake discs and pads, replacing them if severely worn. On the suspension side, it could be aging bushings in the shock absorbers; cracked rubber components tend to make noise on bumpy roads, especially noticeable in rainy weather. If the noise worsens when turning, you should also check if the wheel hub bearing is damaged, as a loose bearing can be dangerous. For safety, avoid DIY fixes and take it to a professional shop for inspection. Ignoring rear wheel noises long-term may lead to brake failure or suspension breakage, compromising driving safety. From experience, many drivers encounter this issue—timely action saves major trouble.
